To all whom it may concern:

Be it known that I, JACOB SCHWARZ, a resident of the city, county, andState of New York, have invented certain new and useful Improvements inSewing-Machines, of which the following is a specification.

In the drawings, Figure 1 is a broken-away rear elevation of asewing-machine embodying my invention. Fig. 2 is a fragmentary frontelevation, on an enlarged scale, of a portion of the sewing-machine,showing the loop carrier and former and their correlated mechanisms.Fig. 2 is a fragmentary side elevation of the cord-cutter-operatingdevices. Fig. 3 is a plan View, partly in section, of the parts shown inFig. 2, the section being taken on, Fig. 3 is the guide forthe.

line 3 3 of Fig. 2. work. Fig. at is a side view of the partsillustrated in Figs. 2 and 3. Fig. 5 is a sectional view of some of theparts shown in Fig. 4, the section being taken on line 5 5 of Fig. 2,showing in detail the loop forming and carrying mechanism. Fig. 6 is asectional view of the loop-carrier. Fig. 7 is a broken-away plan Viewthereof, the said figure also showing the line 6 6, on which the sectionFig. 6 is taken. Fig. 8 is a section on line 8 S of Fig. 1, lookin g inthe direction of the arrow and exhibiting the rotary and oscillatingshafts and their connected-mechanisms. Fig. 9 is a section on line 9 9of Fig. 1, looking in the direction of the arrow, the said view, Fig. 9,showing the same parts as are shown in Fig. 8, the direction of viewbeing opposite to the direction of viewin Fig. 8. Fig. 10 is a sectionon line 10 10 of Fig. 1, looking in the direction of the arrow. Fig. 11is an elevation of the band-severing mechanism for cutting the band asit comes from the needle, the said figure being partly in section andthe section being taken on line 11 11 of Fig. 1. Fig. 12 is a face viewof a waistband produced by the Myinvention relates to sewing-machines,and has for its particular object to produce a sewing-machine which willsew loops on hands of cloth, although the apparatus may be used forother purposes.

The machine shown in the drawings is especially adapted for use insewing loops on folded bands of cloth and for cutting the said foldedbands of cloth into lengths, so as to produce what is known as childrenswaistbands. To this end the mechanism feeds the band, feeds the loopssuccessively to the sewing-point, and sews the said loops into a foldedpart of the band, as will clearly appear from an inspection of Fig. 12,wherein (1 represents a band of fabric, either folded or doubled,havinga folded edge a, under which edge the ends of loops w are insertedand the said edge hemmed down to hold the said loops in place. Thisbandcomes to the needles in one continuous strip, which is severed at theend of each run of eight loops, so as to constitute a waistband havingeight or, if desired, any other suitable number of loops. The machinealso feeds cord, which is cut into lengths and supplied to theloopformer, which loop-former forms the loops, which are carried by aloop-carrier to the sewing-point-that is to say, beneath the needlewherethe needle stitchesthe said loops to the work. These operations will belng-machine, from which rises any usual arm .13, having a head 0, inwhich the needle-operating parts are carried. Working in this head andarm I have shown a rotary shaft D, which operates the needle P (see Fig.2) in any usual manner and communicates motion to an oscillating shaft Eby means of a cam d, working in a yoke 6, (see Figs. 8, 9, and 10,) faston the oscillating shaft E,..or in any other proper manner. I These twoshafts are constantly-moving shafts, and from the oscillating shaft themotions for operating the loop-former, the band-cutter, and cord cutterare taken at predetermined times, as will be hereinafter explained.

Rising from the bed-plate of the machine is a stud F, (shown clearly indotted lines in Fig. 8,) which carries at its lower end a sleeve f,provided with an arm f, carrying a lug f which enters a cam g in acam-wheel G on the main shaft G of the sewing-machine. This cam isclearly shown in plan in Fig. 3 and serves to oscillate the arm f andsleeve f.

This sleeve f (see Fig. 3) carries a slotted arm f in whose slot the endof a link f is adj ustably connected. This link f is secured at itsopposite end to an ear f secured on a' spring J, hung upon the stud Hand bearing against a nut j, (see Figs. 4 and 5,) bears frictionallyagainst the ratchet I. By this means the oscillating motion imparted tothe sleeve f will communicate a step-by-step movement to the ratchet I,so as to step the said ratchet around.

Located below the ratchet I v and secured thereto by screws 43 orotherwise is a loopcarrier plate K, which is hung upon the stud II andsecured to the loop-carrier K by screws or otherwise, the whole rotatingstructure comprising the ratchet, the plate K, the plate f, and theloop-carrier K, being thus secured to rotate together by the movement ofthe pawl-and-ratchet mechanism worked from the oscillating sleeve f.This structure is bedded upon a cam-plate R on the bedplate A. Theloop-carrier K is shown in the present instance as provided with slotsor loop-receivers k for receiving the loop and loop-former and a toothedperiphery for meshing with a removable gear-wheel l, which in turnmeshes with one of a pair of feederwheels m n, the feeder-wheel m beingcarried upon a stud 0, to which a click 1? is pivoted, which clickenters the teeth of the ratchet ,I, so as to prevent backward movementthereof. The other feeder-wheel n is carried upon a spring-pressedpivoted lever q. The cord w, from which the loops are to be formed,passes between these wheels and is fed through the guide Z, beneath thepivoted knife or cutter Z into the guide '1 and the slotted guide Z inwhich the loop-former works. This slotted guide Z is clearly shown inthe side View, Fig. 2. By this means the cord is brought up to thegrooved 1oop carrier K, entering the peripheral groove 10 thereof infront of a slot or loop-receiver 7c.

The knife or cutter Z is pivoted at Z and is pivotally connected at itsrear end to a link l, which is pivoted to one end of ahorizontally-pivoted rod or lever Z", (see Fig. 5,) which in turn ispivoted to an upright link or rod Z held up by a spiral spring Z andpivoted at its upper end to a cam-lever 1 (see ward .and the link Zupward and causing the cutter Z to descend and cut the cord.

Having now described the mechanism for bringing the cord up to theloop-carrier and the cord-cutter, which mechanism supplies theloop-forming mechanism with short lengths of cord, I will now proceed todescribe the said loop-forming mechanism, which operates to formindividually distinct or what I call isolated loops, meaning therebyloops which are separate and distinct from each other and from thefabric from which they were formed. This loop-forming mechanism is shownin the present instance as a loopforming finger 0, which is adjustablycarried in a swinging arm 0 which swinging arm 0 is secured to a block 0pivoted at 0 to a head 0 The block o has pivoted thereto aspring-pressed lever 0 provided with a hook 0 for fitting over a lug 0on the head 0 so as to hold the lever o and finger 0 swung upward in theelevated position shown in Fig. 5 at predetermined times, the said armbeing also provided with a restoring-spring 0 (see Fig. 4,) which issecured to the head 0 so as to throw the said head downward into theposition shown in the said Fig. 4 when the latch or hook 0 has beenreleased from the lug 0 as will be presently explained. The head 0 issupported by a carriage shown as comprising a pair of rods 0 sliding inthe head h and coupled at the rear by a rod to which an arm 0 ispivotally connected. This arm is also pivotally connected to a draw-bar0 which is secured to an arm 0, carried by a hub 0 on the oscillatingshaft M. An abutment 0 (shown in plan in Fig. 3 and in side elevation inFig. 5) projects from the head h into the path of the block 0 whichcarries the arm 0 and the finger 0. This abutment strikes against therear face of the block 0 when the carriage has moved the head 0 andblock 0 to their rear retracted positions, as shown in Fig. 5, andswings the said block 0 so as to tilt the finger o from the positionshown in Fig. 4 to the position shown in Fig. 5 and causes the latch orhook 0 to engage over the lug 0 on the block 0 The head h also carriesatrip-arm, shown in the present instance as an arm 0", (shown in plan inFig. 3 and in side view in Fig. 4,) provided at its forward end with aninturned cam-finger 0 adapted to contact with a pin 0 on the latch 0 sothat as the carriage moves the head and the parts carried therebyforward from the position shown in Fig. to the position shown in Figs. 3and 4 the pin 0 on the latch 0 will strike on the cam-finger 0 therebylifting the said latch and allowing the finger o' to drop forward intothe position shown in Fig. 4.

The operation of the loop-former is as follows: A piece of cord havingbeen brought forward by the feeders into the groove 70 in theloop-carrier and the loop-carrier being in such position that a slot 7cthereof is in line with the slot in the guide Z the shaft M isoscillated by means presently to be described and pulls upon thedraw-bar o ,thereby drawing the carriage backward through the head 71/and causing the finger 0 to come against the section of cord and to drawthe same into the slot 70, thus forming the loop as, which remains inthe slot, as shown in Fig. 3. When the loop has been pulled sufficientlyfar into the slot is to allow its ends to project therefrom apredetermined distance, the face of the block 0 comes against theabutment 0 which rocks the block, thereby swinging the arm 0 and fingero upward clear of the loop-carrier,

so that as the loop-former is returned to its initial position by theoscillating shaft M, which occurs immediately, the arm 0 remains swungup until the pin 0 strikes the loop-carrying mechanisms and theirinteraction, I will now proceed to describe the means whereby they areset in opera tion. It will be obvious that as long as the main shaft Gof the sewing-machine revolves the sleeve f will be rocked and willcontinuously step the loopcarrier around, which loop-carrier, meshingwith the pinion I, will drive the feed-wheels m n to feed the cord intothe guides, and at predetermined times the loop former and cutter areoperated. This loop former and out ter, as will be remembered, areoperated from the rock-shaft M, which is rocked at prededermined timesby the oscillating shaft E in the following manner: The yoke e, which iscarried on the oscillating shaftE, is provided with a lug c, with whicha hook e cooperates. This hook e is pivoted on an arm 6 on therock-shaft M and is shown as provided with an adjusting'screw e and aspring 6 The arm 6 is carried upon the rock-shaft M and is secured to acollar 6 on the said rock-shaft,

which carries a helical spring 6 surrounding the rock-shaft and havingits end a abutting against the framework of the arm 13. A collar e ismounted on the rock-shaft in proximity to the spring e and is providedwith a downwardly-proj ectin g toe 6 (See Figs. 1, 8, and 9.) This toeextends downward into the path of a cam f carried upon a sleeve f hungupon the vertical stud F and supported above the sleeve f thereon by thespiral spring f. The sleeve f is provided with an arm f (see Figs. 3, 8,and 9,) which arm extends into the path of the trips t", carried by thefeed-ratchet I of the loop-carrier, The rock-shaft M also carries acame, (see Figs. 8 and 9,) which cam bears upon the head f of the sleevef so that when the rock-shaft M is rocked this cam 6 will depress thesaid head and sleeve f The swinging sleeve and cam 6 just describedoperate to engage thehook e with hook by reason of the oscillation ofthe oscillating shaft E,'thereby rocking the rockshaft M, operating thecord-cutter Z as explained, and the loop-former.

The engagement and disengagement of' the hook from its lug e areeffected in the following manner: As the loop-carrier rotates in thedirection of the arrow in Fig. 3 it will presently bring one of thetrips t" against the lever f, whereupon as the loop-carrier continues torotate the trip c" will swing the lever f to the right, (see Fig. 3,)thereby rocking the sleeve f and bringing the cam f against the toe cwhich will have the effect of swingin g the said toe and rotating thespring a", the sleeve 6 and arm 6 to swing the hook e and engage it overthe lug e, and as the oscillating shaft E causes the lug e to make anupward movement it will thereby rock the shaft M and cause the saidshaft to operate the cord cutterand loop-former, as has been explained.As the rock-shaft M rocks it will bring the cam 6 against the head f ofthe sleeve f and depress the said head and sleeve, thereby moving thearm f below the path of movement of the trip-lever 2", which engages it,thereby releasing the said trip-lever, which, moving on, allows the armf and sleeve f to swing around to their original positions, to whichthey are restored by the spiral spring f. As soon as the oscillatingshaft swings the lug e downward the spring 6, being uninfluenoed by thetoe e and its collar 6 will throw the hooke outward clear of the path ofmovement of the oscillating lug 6, so that the said lug e will notcommunicate any further motion to the hook until the said hook has beenrengaged therewith by another trip 2' coming in contact with the lever fand swinging the sleeve f and its connected parts, as described.

Before describing the band-cutterI will proceed to describe thesem'azfim operations of pro ducing the waistband. The work a comes in astrip or band to a guide or folder 0, where it is folded and passesbeneath the needle-bar and needle P and work-advancing mechanism orpresser-foot' Q. The loops t are inserted beneath the edge a by theloop-carrier and the said edge felled or hemmed down by the needle, theloop-carrier revolving continuouslyand being filled with loops by meansof the loop-former, which as the loop-carrier revolves is given a quickoscillating motion,

as explained, drawing a length of cord which has been fed to theloop-carrier and chopped off by the knife or cutter 1* into a slot orlooprec'eiverk' of the loop-carrier, from which its ends project, theloop-former returning to its initial position by another quick movement,as explained, the feed-wheels meantime feeding forward the cord to bringanother short length up to the loop-carrier, which short length is .cutoff by the cutter Z before the loop-former again operates.

In order to make certain that the ends of the loops are fully insertedbetween the folded edge a of the band and the body a thereof, I providethe loop-carrier with sliding bolts 70 alongside the slots 70, (seeFigs. 6 and 7,) so that when the ends of the sliding bolts 70 projectbeyond the periphery of the loop-carrier they will serve to brace theends of the loop,

. so as to insert them properly in the band bethe sewing of the loop bythe needle.

ing sewed. It is essential, however, that the bolts be withdrawn withinthe periphery of the loop-carrier before the loops reachthe needle. ThisI have provided for as follows: Each bolt is provided with a springforcing it inward, and also with a bowl k hearing against thestationarycam R on the bedplate, which cam is so located with respect tothe needle that as the loop-carrier rotates the bowls of the slidingbolts will come against the portion 1" of the cam, so as to thrust thesaid bolts outward to support the loop laterally until when the loop isabout to go under the needle the bolts come opposite the trip 1. of thecam and are sprung inward by their springs, so that they will notinterfere with The band comes from the needle with the'loops sewedthereon, as shown in Fig. 3, and the band passes through a cutter,(shown in Figs. 1 and 11,) which cutter is shown as consisting ofparallel guides S S, in which a knife 3 Works vertically. This knife isnormally held up by springs s and receives the thrust of a cam-lever 8which is pivoted at s and has its rear end 5 projecting into the path ofa cam 5 carried upon an arbor 3 which arbor carries aratchet 8 Locatedadjacent to the ratchet is a pivoted lever 5 which carries a pawl 8engaging with the ratchet. The lever 8 is oscillated by a link s ,\vhichreceives an oscillating motion from an arm 8, which is fast on therock-shaft M, which, as it will be remembered, is oscillated atpredetermined times by the hook e engaging with the lug e on theoscillating shaft E.

The operation of this band-cutter is as follows: At each oscillation ofthe rock-shaft M the pawl steps the ratchet 5 around one tooth, so thatthe said ratchet makes one complete revolution for every eightoscillations of the shaft M, and on the eighth step the knife sis forceddown by the cam-lever 5 which works in response to the cam 8 so thatsince as each loop is sewed in the band the rock-shaft M is oscillatedthrough the medium of a trip 5 of the loop-carrier it will be readilyapparent that the band-cutter s will divide or sever the band at the endof each section of eight loops, so as to produce a waistband such as isexhibited in Fig. 12. It will be apparent,

however, that I have simply adopted eight loops arbitrarily and that themachine can be adjusted to cut the band into any desired length.
